TIME-LOCK.

SPECIFICATION forming part of Letters PatentNo. 567,623, dated September 15,1896. Application filed January 2, 1895. Serial No. 533,601. (No model.)

To all whom t may concern:

Be it known that I, EMORY STOCKWELL, a citizen of the United States, residing at Stamford, in the county of Fairfield and State of Connecticut, have invented a new and Improved Time-Lock, of which the following is a specification.

My invention has for .its object to produce a time-lock Which Will be very simple in construction and operation and embrace the lock proper and'time-controlling mechanism fixed in such relation as to be always in proper adjustment and ready to be applied to the receptacle to be locked.

My invention Will be fully understood upon reference to the accompanying drawings, forming part of this specification, in which- Figure l is a face view of the improved lock and time controlling` mechanism. Fig. 2 is an edge view of the same. Fig. 3 is a detail sectional View of the lock proper and a portion of the mounting. V

Any suitable form of time mechanism may be employed and fixed upon a mounting 1, which is preferably in the form of an angleplate, such, for instance, as the time mechanism 2, which comprises suitable power 3 upon aWinding-arbort, and suitable controlling mechanism 5 5. Upon the time mechanism, or in convenient relation thereto, I mount a dial 6, adapted to rotate upon a bearing 7, on Which it is secured by a nut 3. This dial 6 has marked upon its face periods of time, preferably hours, and upon its periphery it is provided with teeth 9 of sufficient number to cause the rotation of the dial at a rate corresponding to the periods inscribed upon its face. I have shown the dial pro vided with twenty-four hour periods and arranged it to revolve in twentyfour hours; but it is obvious that it might readily be made to revolve in fifty-six, seventy-two, or any other desired number of hours. The dial G is driven by a pinion 10 upon the Windingarbor 4, such pinion being constructed with proper regard for the object to be attained by the dial 6. The dial 6 is `further provided with an actuating' tooth or projection l1 for operating the lock, as will now be described.

The lock proper comprises a dog l2, fulcrumed upon a pivot 13 and having a hooked lookin g end let, which is held normally in locking position against a stop l5 by means of a spring 16. The dog l2 is further provided with a projecting stud 17, which, When the dog is moved upon its pivot 13, may move in a slot 18, formed in the casing 19.

I have stated thatthe mounting 1 is preferably in the form of an angle-plate, and I have shown the time mechanism mounted upon one part of said angle-plate. In order to fix the lock in operative relation to the time mechanism and have it constantly under the control thereof, it is simply necessary to fix the lock uponv the other portion of the angle-plate, With the projecting stud 17 in the path of the tooth l1 on the dial 6. Vhen this is done, the parts are fixed in proper relation, and the combined mechanism is ready for use by simply attaching the angle-plate With the locking-dog l2 in proper relation to a keeper, such as 20, Which may be secured to the cover or door of the closure.

I have shown the use of one movement for controlling the lock; but it is obvious that` 75 two or more movements might be connected to the unlocking mechanism in any manner which is noW Well known to the art. Itis further obvious that the exact construction of the time mechanism is immaterial, it being simply necessary to have any mechanism which will drive the operating dial for any desired number of hours.

By organizing the parts upon an angleplate the lock and time mechanism are selfcontained and need no adjustment. There is a direct engagement between the lockingdog and operating dial, and the stud on the dog operates as a pointer for Winding the lock, yet the lock and time mechanism are entirely independent, except at the moment of unlocking.

Having thusdescribed my invention, the following is What I claim as new therein and `desire tol-secure by Letters Patent l. In combination With a lock-attaching plate having a lock thereon, a shelfor snpport fixed rigidly at Van angle thereto, and a time -lock operating mechanism mounted upon said shelf or support and constructed to engage the lock, as shown and described.

2. In a time-lock the combination of the rotating dial, of the time mechanism, the pivotally-supported locking-dog extending at right angles to the plane of the dial and provided with a spring for holding it normally in locking position, a stud projecting from the side of the locking-dog in the plane of the dial, and a tooth on the dial adapted to engage the stud and unlock the dog, substantially as set forth.
